    Study Notes

    Physics Study Notes

    • Physics is the scientific study of matter and energy, and their interactions.
    • It's a broad field encompassing various sub-disciplines.
    • Key concepts include motion, forces, energy, waves, and the structure of matter.

    Units and Measurements

    • Fundamental physical quantities include length, mass, time, electric current, temperature, amount of substance and luminous intensity.
    • Fundamental units include the meter (m) for length, kilogram (kg) for mass, second (s) for time, ampere (A) for electric current, Kelvin (K) for temperature, mole (mol) for amount of substance, and candela (cd) for luminous intensity.
    • Derived units are combinations of fundamental units, like velocity (m/s).
    • SI units are the standard international system of units.

    Motion

    • Velocity is the rate of change of displacement.
    • Speed is the rate of change of distance.
    • Acceleration is the rate of change of velocity.
    • Equations of motion relate initial velocity, final velocity, acceleration, time, and displacement.

    Forces

    • Force is a push or pull that causes an object to accelerate.
    • Newton's laws of motion describe the relationship between force, mass, and acceleration.
    • Newton's law of universal gravitation describes the force of attraction between two objects with mass.

    Energy

    • Energy is the capacity to do work.
    • Various forms of energy exist, including kinetic energy, potential energy, thermal energy, and electromagnetic energy.
    • Conservation of energy states that energy cannot be created or destroyed, only transformed.

    Waves

    • Waves are disturbances that transfer energy.
    • Types of waves include transverse waves and longitudinal waves.
    • Wave properties include amplitude, frequency, wavelength, and speed.

    Matter

    • Matter is anything that has mass and occupies space.
    • Structure of matter at the microscopic level is studied in terms of atoms and molecules.
    • States of matter include solid, liquid, and gas.

    Thermodynamics

    • Thermodynamics studies heat and its relation to other forms of energy.
    • There are four laws of thermodynamics that describe the fundamental principles of thermodynamics.

    Electricity and Magnetism

    • Electricity is the study of charges and their interactions.
    • Electromagnetic forces bring together electricity and magnetism as a single force.
    • Electric circuits follow the laws related to electricity.

    Optics

    • Optics studies light, its behavior, and its interaction with matter.
    • Various phenomena associated with light (reflection, refraction, diffraction, etc.) are discussed under this branch.

    Modern Physics

    • Modern physics encompasses relativistic mechanics and quantum mechanics.
    • Relativistic mechanics is the study of motion at speeds approaching the speed of light.
    • Quantum mechanics describes the behavior of matter and energy at the atomic and subatomic levels.
